JEREMIAH M. BAKER, OF LAFAYETTE HILL, PENNSYLVANIA.

OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 783,237, dated February 21, 1905.

Application filed July 2, 1904. Serial No. 215,110.

To (all whom it may concern:

Be it known that I, J EREMIAR M. BAKER, a citizen of the United States, residing at Lafayette Hill, county of Montgomery, and State of Pennsylvania,have invented a certain new and useful Improvement in Oil-Cans, of which the following is a specification.

My invention relates to a new and useful improvement in oil-cans, and has for its object to provide an oil-can in which the oil may be drawn from the same by compressed air; and a further object of my invention is to so construct the can that it will be extremely simple and cheap to manufacture, while at the same time beingefiicient and durable, and is not liable to get out of order, as the parts are few in number and easily accessible for repairing.

lVith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of my improved oil-can; Fig. 2, a similar view to Fig. 1, showing a modified form of air-pump.

A represents the body of the can, which may be of any shape desired, closed at the upper and lower end.

B is the air-pump, which in one form lies horizontally on the top of the can, a pipe B at one end extending downward through the top of the can, and this pump is designed to be operated by a handle B, secured directly to the piston.

C is the supply-pipe, which extends downward through the top of the can and reaches to a point near the bottom thereof. 0 is a stop-cock located within this pipe C upon the outside of the can.

is a movable spout connected to the top of the pipe C. This spout may be either placed in position so that the outer end will be beyond the periphery of the can, as shown in full lines in Fig. 1, or may be turned over the top of the can, as shown in dotted lines.

D is a safety-valve which is formed of a single piece of resilient material attached at one end to the top of the can, the spring of which allows the air to escape after a certain amount of air-pressure has been attained upon the inside of the can. A stop D is provided to limit the upward movement of the valvestrip.

E is a screw-cap closing an opening through which the can may be filled.

In operation the can is filled with oil to a point near the top, leaving'a certain amount of space between the top of the can and the oil. Then the stop-cock C is closed, and air is forced into the space at the top of the can by means of the pump B, thus compressing the air between the oil and the top of the can. Then by opening the cock C oil may be drawn until the oil-level has been lowered sufficient to allow the compressed air to regain its normal volume. Then the space must again be filled with compressed air by means of the pump.

In Fig. 2 I have shown a modified form of pump construction in which the pump B extends downward vertically into the can and the piston-rod is connected to a lever F, pivoted to the top of the can.

Of courseI do not wish to be limited to the exact construction here shown, as slight-modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is In an oil-can, an air-tight receptacle, a discharge-pipe in communication with the interior of the receptacle, means for compressing air within the receptacle said receptacle having a vent in its top, a safety-valve for the vent consisting of a strip of resilient material attached at one end to the top and resting over the vent, and a stop for limiting the movement of the valve or strip in one direction.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

JEREMIAH M. BAKER.
